Optionally, the electronic device 200 further includes a controller disposed inside the housing, and a connector through which the controller is electrically connected to the driving device. The driving device is connected to the controller of the electronic device 200, which facilitates the controller of the electronic device 200 to control the driving device, so that the driving device drives the color filter ribbon 2 to move to a proper position, and the light of the light source 1 passes through the target color region to change the color of the light source 1.

The controller of the electronic device 200 supplies power to the light emitting assembly 100 and transmits signals, thereby realizing control of the light emitting assembly 100, and simultaneously, the connection relationship between the controller and the light emitting assembly 100 is relatively simple.

Optionally, the driving device includes a motor circuit board 4, the controller is a main circuit board 6, the connector is a board-to-board connector, and the motor circuit board 4 is connected to the main circuit board 6 through the board-to-board connector. Wherein the board-to-board connector includes a female socket 51 and a male socket 52. For example, the female socket 51 is disposed on the main circuit board 6, the male socket 52 is disposed on the motor circuit board 4, and the female socket 51 and the male socket 52 are connected in a fitting manner.

For example, when the electronic device 200 is a mobile phone, the user can select the light color of the flash lamp desired by the user through the mobile phone interface; then, the controller of the mobile phone controls the driving device, so as to control the movement of the color filter ribbon 2, and move the target color region of the color filter ribbon 2 to the front of the flash lamp, so as to change the light color of the flash lamp. After the flash lamp works, the user can choose to change the light color of the flash lamp. For example, when the target color region is located on the left side of the flash lamp, the motor on the opposite side rotates to move the target color region to the front of the flash lamp, and the flash lamp continues to emit light for the next time. When the light color of the flash lamp does not need to be changed, the target color area is a transparent color area, and the transparent color area can be moved to the front of the flash lamp.

The controller is programmed, so that the light-emitting mode of the flash lamp can be controlled more freely and flexibly.

The lighting assembly 100 of the present application has two main usage scenarios: first, the electronic apparatus 200 shoots a flash; second, the flashlight is always on as a flashlight. When the light emitting assembly 100 adopts the first usage scenario, first, the user uses the shooting application, turns on the flash function at the interface of the shooting application, and then selects a desired color. When the color selection is finished, the driving device starts to work, and the corresponding target color area is moved to the front of the flash lamp; and finally, the flash lamp flashes along with the shooting instruction triggered by the user so as to change the shooting color. If the user continues to use the color-selecting stage, otherwise, the process is ended, and the transparent color area is moved to the front of the flash lamp. When the light emitting assembly 100 adopts the second usage scenario, that is, when the user uses the flashlight function, after the user turns on the flashlight function and selects the color of the flashlight on the function interface, the driving device starts to operate, the corresponding target color region is placed in front of the flashlight, and then the flashlight starts to normally light. If the user wants to switch the color, the user returns to the color selection interface, the process is repeated, after the user finishes using the flashlight function, the flash lamp is turned off, and the driving device drives the transparent color area of the filtering color band 2 to be arranged in front of the flash lamp.

In this embodiment, the light emitting assembly 100 is disposed in the housing of the electronic device 200, so that inconvenience of carrying an external filter or an external light source 1 when taking a picture or using flashlights with different colors is avoided. The driving device drives the filtering color band 2 to move, so that the structure is simple, the operation is convenient, and the size of the electronic device 200 is reduced.
